What is parallelogram method in physics?
Parallelogram method is a method for finding sum or resultant of two vectors. The polygon method is a method for finding sum or resultant of more than two vectors. (Can be used for two vectors also).
What is the parallelogram law formula?
The Parallelogram law states that the sum of the squares of the length of the four sides of a parallelogram is equal to the sum of the squares of the length of the two diagonals. In Euclidean geometry, it is necessary that the parallelogram should have equal opposite sides. 2(AB)2 + 2 (BC)2 = (AC)2 + (BD)2.
What is a parallelogram and its properties?
Convex polygon

What is parallelogram law in functional analysis?
In mathematics, the simplest form of the parallelogram law (also called the parallelogram identity) belongs to elementary geometry. It states that the sum of the squares of the lengths of the four sides of a parallelogram equals the sum of the squares of the lengths of the two diagonals.
What is the law of area of parallelogram?
To find the area, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply. The base and height of a parallelogram must be perpendicular.
What is parallelogram law of forces definition?
If two forces, acting at a point, are represented in magnitude and direction by the two sides of a parallelogram drawn from one of its angular points, their resultant is represented both in magnitude and direction by the diagonal of the parallelogram passing through that angular point.
What is parallelogram law for addition and Triangle law?
Their sum, \vec{a} + \vec{b} is represented in magnitude and direction by the diagonal of the parallelogram through their common point. Hence, we can conclude that the triangle and parallelogram laws of vector addition are equivalent to each other.
What is called parallelogram?
A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal). A quadrilateral with equal sides is called a rhombus, and a parallelogram whose angles are all right angles is called a rectangle.
What is parallelogram diagram?
A parallelogram is a special type of quadrilateral that has equal and parallel opposite sides. The given figure shows a parallelogram ABCD which as AB parallel to CD and AD parallel to BC. We also see a lot of parallelogram like shapes and objects around us.
How is the parallelogram method used in physics?
The parallelogram method is the graphic method of finding the resultant of two vectors that do not act along a straight line.The parallelogram law is a rule that states that if two vectors are adjacent to one another, then they can be added together head to tail to find the resultant by drawing a line…
Is the head to tail method the parallelogram method?
As I mentioned previously, the head-to-tail method and parallelogram method are identical. This is especially obvious when summing two vectors. Using the above applet, sum two vectors and watch carefully.
Which is the formula for a parallelogram without height?
Its formula is: Area = Base x Height (in square unit) The area of a parallelogram without height is given by: Area = ab sin x Where a and b are the two adjacent sides of parallelogram and x is the angle between them.
How are the opposite sides of a parallelogram equal?
The opposite sides of a parallelogram are equal in length, and the opposite angles are equal in measure. Also, the interior angles on the same side of the transversal are supplementary. Sum of all the interior angles equals 360 degrees. A square and a rectangle are two shapes which have similar properties of a parallelogram.
